Hi folks, Thanks all for your comments.
Here we go, just as Montreal city does, we"ll think about it (mostly licence considerations) before taking actions: We've added an entry in Import catalog: http://wiki.openstreetmap.org/wiki/Import/Catalogue#Ongoing_Imports.2C_Semi-Automated and started a new wiki mapping project's page: http://wiki.openstreetmap.org/wiki/Arrondissements_Quebec_city_import Cheers!
